Jeremiah 17:5 (NIV)
The etymology of the word is often understood as "lacking worth", from two common words: beli- (בְּלִי "without-") and ya'al ( יָעַל "to be of value").
""Belial" is applied to ideas, words, and counsel, to calamitous circumstances, and most frequently, to worthless men of the lowest sort, such as men...in general who stir up contention." - Wikipedia: Belial/Hebrew Bible.
What are worthless and wicked people like? They are constant liars.
